Marketability belongs to the economic sphere and never opposes musical value

Evidence

There is no ‘use-value’ in this sphere; what could appear as such, namely the ‘marketability’ of this symphony or that Chopin étude, has nothing to do with musical value. Marketability is also not suppressed by ‘exchange-value’, but rather is a part of this realm, the sphere of the quantitative, of measurable success. — Dirk Braunstein, Adorno’s Critique of Political Economy, 457
